Line Lightning Protection
Overview
Lightning striking overhead lines caused by lightning over-voltage or over-voltage can easily lead to insulator flashover or breakdown, power frequency arc concentrated in the insulation layer of the breakdown point caused by insulation lines melting broken. In order to prevent this accident, the need for overhead lines on the air circuit over-voltage protection device, its role is in the lightning overhead insulated lines, the lightning current to the protector, and cut off the power flow, to avoid the insulator flash or hit Wear, protect the overhead lines, to avoid disruptions.

The fuse elements used in most distribution cutouts are tin or silver alloy wires that melt when subjected to high enough current. Ampere ratings of fuse elements vary from 1 ampere to 200 amperes.
Standards
Up until the mid-1990s each manufacturer used their own dimensional standards for cutout design; by the late 1990s most cutouts were of an "interchangeable design". This design allows for the interchangeable use of cutout bodies and fuse holders manufactured by different vendors.

Products FAQ
Used on overhead transmission lines and taps to protect distribution transformers from current surges and overloads,An overcurrent caused by a fault in the transformer or user circuit can cause the fuse to melt and the switch mechanism to visibly open,Disconnect the transformer from the line. The device can also be opened manually by a utility line worker standing on the ground and using a long insulating rod called a “ground rod”.
